Procurement Notes

Verify the specific datasheet version for accurate mechanical drawings and electrical tolerances before finalizing designs. Confirm that the 8-ohm impedance matches the amplifier output stage requirements. Ensure the operating temperature range of -20°C to +60°C aligns with the intended environment. Check for any RoHS compliance documentation if required by regional regulations. Validate the soldering process parameters to protect the paper cone material during assembly.

Selection Notes

Select this component when a general-purpose, low-profile speaker is needed for board-level integration. The 8-ohm impedance is standard for many audio driver circuits. Consider the 78 dBA sensitivity for applications where moderate volume is sufficient without complex amplification. The paper cone offers a specific acoustic characteristic distinct from polymer alternatives. Evaluate the 2W power rating against peak signal demands to prevent distortion or damage.

Part Context

This model belongs to the AS series of speakers from PUI Audio, Inc., which focuses on compact, cost-effective audio solutions. The AS series typically includes various sizes and impedances to suit different form factors. This specific part represents a mid-range size option within the portfolio, balancing size and acoustic performance for embedded audio tasks.

Replacement Considerations

Direct substitutes may include other 8-ohm, 2W speakers from PUI Audio with similar dimensions, such as the AS01508MR-R or AS01308MR-R, though their sensitivity and frequency responses differ. Cross-manufacturer replacements require matching impedance, mounting style, and physical envelope constraints to ensure compatibility with existing PCB layouts and acoustic enclosures.
